所以我有一个带有很多标记的MapView,其中大多数都集中在英里宽的簇中.缩放时,标记重叠并且看起来只有一个.我想要实现的是在某个缩放级别用一个组标记替换重叠标记,组标记将显示标记的密度,onClick将缩放以显示内部的所有标记.我知道我可以用蛮力距离测量做到这一点,但必须有一种更有效的方法.任何人都有任何解决方案或智能算法如何实现这一目标？

我有一张谷歌地图上有这些项目:

drawable3 = this.getResources().getDrawable(R.drawable.trazeicon);

但是自动地,Android trazeicon在地图上绘制了图像的阴影,我不想拥有那个阴影.

我该如何删除它？

编辑:

我收到了错误: Syntax error, insert "}" to complete ClassBody

这是完整的代码:

package com.GPSLoc;

import java.util.ArrayList;

import android.app.AlertDialog;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Rect;
import android.graphics.drawable.Drawable;

import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.MapView;
import com.google.android.maps.OverlayItem;

public class MyItemizedOverlay extends ItemizedOverlay {


    private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
    private Context mContext;

    public MyItemizedOverlay(Drawable defaultMarker) {
        super(boundCenterBottom(defaultMarker));
    }

    protected OverlayItem createItem(int i) {
      return mOverlays.get(i);
    }

    public int size() {
      return mOverlays.size();
    }

    public void addOverlay(OverlayItem overlay) {
        mOverlays.add(overlay); …

并告诉我正确的模拟器规范...它可以是模拟器的错误......

我正在尝试构建需要标记聚类的应用程序,所以我已经尝试了很多次阅读Google API创建演示但每次显示错误都建议我也是Web应用程序使用map API v3聚类标记哪个API我必须使用API​​ v2或apiv3的地图来构建应用程序,请帮助我,我是Android新手或给我一些链接,我可以找到我的解决方案
